Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes

open access: yesAdvanced Functional Materials, EarlyView.
Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.

Structural Design and Horizontal Wave Force Estimation of a Wall-Climbing Robot for the Underwater Cleaning of Jackets

open access: yesJournal of Marine Science and Engineering
Currently, divers face significant safety risks when cleaning marine organisms from the steel structures of offshore underwater platform jackets. Consequently, utilizing robots instead of divers to carry out underwater biofouling removal operations will ...

An Electrowetting Pump

open access: yesAdvanced Functional Materials, EarlyView.
A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

3D Hydrodynamic Flow Lithography

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Continuous‐ and stop‐flow lithography are widely used to fabricate multi‐dimensional microstructures whose cross‐sectional morphology is dictated by the flow profile of multiple co‐flowing streams. Here, we introduce three‐dimensional hydrodynamic flow lithography (3D HFL), a platform for programmable generation of multi‐layered flow profiles ...

Reconfigurable Au Nanoparticle Monolayers on Regenerated Cellulose Hydrogels: Highly Sensitive SERS Detection of Polystyrene Micro/Nanoplastics With Interpretable Deep Learning

open access: yesAdvanced Functional Materials, EarlyView.
A regenerated cellulose (RC) hydrogel‐based SERS substrate integrating a Marangoni‐transferred gold nanoparticle self‐assembled monolayer (Au‐SAM) is fabricated. Reswelling‐induced hotspot formation enhances polystyrene micro/nanoplastics (PS MNPs) detection in complex matrices, providing reproducible, high‐throughput SERS signals across diverse ...

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

open access: yesAdvanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

FLOOR CLEANING ROBOT

open access: yes, 2019
An automatic cleaner robot is used for cleaning a room or area with minimal human intervention. Such a robot will execute tasks like vacuuming and mopping to keep the room clean. A path planning algorithm is executed for the robot to find out the layout of the room or area by itself.

Engineered Nanotopography to Modulate Growth and Signaling of Neuronal Networks

open access: yesAdvanced Functional Materials, EarlyView.
This study examines the interaction between neurons and nanoscale topographies on engineered substrates. Neurons cultured on nanowires, nanopillars and nanoneedles exhibit enhanced neurite outgrowth, form more organized neuronal circuits, and display improved synaptic connectivity, compared to flat substrates.
